Study Notes
General Principles
- The musculoskeletal exam evaluates the patient's posture, gait, and the function of each joint.
- It focuses on symmetry and any signs of inflammation, pain, or limitations in range of motion.
- The exam includes inspection, palpation, range of motion, and special tests.
- The clinician assesses gait, posture, and body symmetry.
- Examination includes inspection, palpation, range of motion, and special tests.
Specific Joint Examinations

Common Musculoskeletal Disorders
-
Case Studies and Clinical Scenarios focus on history and physical exam of various conditions including:
- Low back pain
- Neck pain
- Shoulder pain
- Knee pain
- Ankle pain
- Wrist pain

Common Childhood Orthopedic Disorders
Clubfoot
- Evaluation uses clinical examination to assess the severity of the deformity.
- Risk Factors and Indications for Imaging include family history, associated syndromes, and difficulty with correction.
- Imaging is used to rule out other conditions, like congenital vertebral anomalies, and is typically ordered in severe or complex cases.
Slipped Capital Femoral Epiphysis (SCFE)
- Diagnosis and Management involve hip pain that is often referred to the knee, and limited internal rotation of the hip.
- Treatment focuses on surgical pinning of the epiphysis.
Scoliosis
- Diagnosis and Management involve screening for spinal deformities, and treatment options range from observation to bracing to surgery, depending on the severity.
Limb Length Discrepancy
- Diagnosis and Management are based on clinical measurements and imaging studies.
- Treatment aims to correct the length discrepancy, either through growth modulation or surgical intervention.
Common Causes and Risk Factors For Low Back Pain
Mechanical Low Back Pain
- Includes pain caused by disc herniation, spinal stenosis, and muscle strain.
- Risk Factors are often degenerative changes in the spine, overuse, poor posture, and obesity.
General Risk Factors For Low Back Pain
- Family History is a significant factor.
- Age and pregnancy are also contributing factors.
- Obesity, smoking, and lack of physical activity all increase the risk.
Identification of Red Flags In Clinical History
Age-Specific Concerns
- Sudden onset of back pain in older adults may signal a fracture.
- In younger individuals, concern for infection or tumors.
Use of Anticoagulants
- Increases the risk of spinal epidural hematoma.
Constitutional Symptoms
- Fever signifies infection.
- Weight loss points to cancer.
- Fatigue suggests systemic illness or metabolic disorders.
Key Physical Examination Findings
Neurological Evaluations
- Weakness in the legs may indicate spinal cord compression.
- Sensory changes, like numbness or tingling, suggest nerve root involvement.
- Loss of bowel or bladder control signifies cauda equina syndrome.
Genitourinary Symptoms
- Urinary incontinence or retention are red flags for spinal cord compression.
Specific Conditions Associated with Red Flags
Spinal Epidural Abscess
- Characterized by severe back pain, fever, and neurological deficits.
Cauda Equina Syndrome
- Represents a serious condition affecting the nerves in the low back.
- Signs include saddle anesthesia, bowel and bladder dysfunction, and leg weakness.
Vertebral Compression Fractures
- Occur due to trauma or osteoporosis.
- May present with sudden onset of back pain, especially in older adults.
Malignancies and Metastatic Disease
- Back pain is a common symptom that is often persistent and worsens over time.
- Other signs include weight loss, fever, and fatigue.
Comprehensive Guide to Conducting an Office-Based Musculoskeletal Exam
- A detailed musculoskeletal exam is critical for diagnosing and managing various conditions affecting the shoulder, spine, and upper extremities.
